Let A and B be sets, let R and S be relation on A and B, respectively, and let f:A be a function. The function f is relation preserving if x R y if and only if f(x) S f(y), for all x, y∈A. (1) suppose that f is bijective and relation preserving. Prove that f^(-1) is relation preserving.

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
